offset bushings

Well if it makes you feel any better, I just rebuilt the whole front end on my 71 R/T charger and went back with standard bushings. A previous owner rebuild had the offset bushings installed in either the front or rear only of the upper arms.(don't recall front or rear) I was unaware of the offset bushings previously installed and just ordered a standard kit for replacement so I went with it. Id also like to comment that I assumed you use a total of "4" offset bushings when going the offset route????? or do you use only 2????
